11 WHAT ARE WATER SERVICE LINES?

12 WATER SERVICE LINES DEFINED A pipe, hose, tube, or other line for conveying water Other appurtenances include Corp and Curbstop valves Normal potable water pressure to a home ranges from psi or 413 to 585 kpa

13 WATER SERVICE LINES

14 SIZING THE WATER SERVICE PIPE The minimum size for a water service pipe is 3/4" and this will likely be sufficient for most residential

15 SIZING THE WATER SERVICE PIPE Factors to consider when Sizing: Total water demands of all the fixtures, appliances, auxiliary uses and future demand possibilities. Pressure supplied to the building and if it fluctuates throughout the day Rise in elevation to the highest fixture, from the point where it enters the building

16 MINIMUM WATER SERVICE SIZE REQUIRED FOR RESIDENTIAL STRUCTURES Class of Building Minimum Service Class of Building Size - Internal Diameter Peak Hour Pressures > 350 kpa Minimum Service Class of Building Size - Internal Diameter Peak Hour Pressures < 350 kpa Single-Family Dwelling 20 mm 25 mm Two-Family Dwelling (Duplex) Two separate 20 mm Two separate 25 mm Four-Family Dwelling (Fourplex) 40 mm 40 mm

17 RESIDENTIAL STRUCTURE SIZES A larger service size than that indicated in Table 3 will be required where, in the opinion of the Engineer, the length of the service pipe, the potential demand, the supply pressure or other conditions warrant an increase.

18 COMMERCIAL & INDUSTRIAL STRUCTURES Water services for industrial, commercial, or institutional applications shall be sized and located according to all relevant codes and regulations and in accordance with current industry standards as presented in AWWA Manual M22 and shall be subject to approval by the Engineer.

19 WATER SERVICE LINE MAIN COMPONENTS Typically only three joints required in the underground portion, and they are usually brazed, compression or flared joints

20 WATER SERVICE MAIN COMPONENTS Corporation Stop Gooseneck Curb Stop Main Shut Off

21 WATER SERVICE MAIN COMPONENTS Corporation Stop The valve installed on the water main by the municipality. This is usually done under pressure using a "Live Tapping" device.

22 WATER SERVICE MAIN COMPONENTS Gooseneck/Frost Loop - An arched bend in the water service is typically installed to prevent strain on the corporation stop from soil movement and pipe expansion.

23 WATER SERVICE MAIN COMPONENTS CONT D Curb stop is a quarter turn ball valve that can be fitted with a valve key to turn on/off the water and is protected by a small diameter valve box that extends to height of the finished grade.

24 WATER SERVICE MAIN COMPONENTS CONT D Main Shut Off - As soon as the water service enters the building an isolation valve must be installed inside the building.

25 WATER SERVICE LINE CONSTRUCTION MATERIALS Prior to the 1950s, lead was commonly used for water service piping, Copper was also used Today s preferred materials are copper and certain polyethylene pipes. The underground water service pipe is installed below the frost line, most often with Type K or Type L soft copper and more recently PEX

26 WATER SERVICE LINE CONSTRUCTION MATERIALS CONT D Lead is a toxic metal that is harmful to human health; there is NO safe level for lead exposure. Water may absorb lead from services pipes potentially increasing the concentration of lead in tap water above Health Canada s standard. The best long-term solution is to replace lead service pipes.

27 HOW TO DETERMINE IF YOUR SERVICE PIPE IS LEAD 1. Locate the emergency water shut-off valve or water meter in your home (usually found in the basement). 2. Check the colour of the pipe coming out of the ground and into the meter you may have to lightly sand the surface.

28 HOW TO DETERMINE IF YOUR SERVICE PIPE IS LEAD If the pipe is: The colour of a Canadian penny it s copper Bright blue or black it s likely plastic tubing (polyethylene) Grey it s galvanized iron or lead

29 HOW TO DETERMINE IF YOUR SERVICE PIPE IS LEAD The next indicators are the hardness and fittings. Don't attempt to test the hardness of your pipe if you suspect it's plastic. If it s a lead pipe, you ll be able to etch gently into the pipe with a sharp-tipped object

31 WATER SERVICE LINE CONSTRUCTION MATERIALS CONT D AWWA C901 Polyethylene (PE) Pressure Pipe and Tubing, ½ In. (13 mm) Through 3 In. (76 mm), for Water Service AWWA C605 Underground Installation of Polyvinyl Chloride (PVC) Pressure Pipe and Fittings for Water

32 ARE SERVICE LINES AND WASTEWATER LATERALS REGULATED ON FIRST NATION LANDS? Ontario Building Code Safe Drinking Water Act Guideline for Safe Drinking Water On First Nations Protocol for Centralised Drinking Water Systems in First Nations Communities; Protocol for Centralised Wastewater Systems in First Nations Communities; and Protocol for Decentralised Water and Wastewater Systems in First Nations Communities.

33 APPLICABLE CODES Ontario Building Code - OBC, WATER PIPE SIZING REQUIREMENTS DESCRIBED IN PART 7 OF THE ONTARIO BUILDING CODE.

34 WHAT ARE WASTEWATER/SEWER LATERALS?

35 WASTEWATER/SEWER LATERAL DEFINED Sewer line that carries black and grey wastewater from the sanitary fixtures and floor drains inside your home to the communal wastewater collection mains or to a nearby septic system. Toilet waste is black water Grey Water includes; showers, laundry, brushing your teeth, dishwashing, housekeeping etc.

36 WASTEWATER/SEWER LATERAL DEFINED Typical Septic System

37 WASTEWATER/SEWER LATERAL SIZING OBC Minimum Size of Building Drains and Sewers (1) Every sanitary building drain and every sanitary building sewer shall be at least 4 in. (100 mm) size. (2) Every storm building drain and every storm building sewer shall be at least 4 in. size. (100 mm)

38 WASTEWATER/SEWER LATERAL SIZING Maximum Permitted Hydraulic Load Drained to a Horizontal Sanitary Drainage Pipe Ontario Building Code Table outlines the max load

39 WASTEWATER LATERAL PIPE SELECTION AND DESIGN Based on the following criteria; Sewer Pipes and Appurtenances Rigid Pipe Design Flexible Pipe Design Minimum 1% grade and Maximum of 2% Minimum of 1% would provide a flow rate of between 2 and 3 ft/sec

40 WASTEWATER LATERAL PIPE SELECTION AND DESIGN Other Considerations include; Pipe Depth Pipe Location Pipe Bedding

41 TYPES OF WASTEWATER LATERAL PIPES Type of pipe varies by the age of your house Clay, cast-iron, or plastic sewer pipe have been and still are used Clay and cast-iron are older types; plastic is the newest

42 TYPES OF WASTEWATER LATERAL PIPES CONT D In terms of home renovation, you may find yourself being steered in the direction of PVC or ABS plastic pipe over clay and cast-iron. While plastic pipe is undoubtedly easier to work with, clay and iron have strong points: long lifespan and strength (for the iron).
